I patched up the Cygwin version to allow for unlimited-time file
diffing, and a keep-alive process in the meantime to keep an SSL
session/connection up. A pretty much randomly-modified 550MB file takes
about 15 minutes to diff completely, with, effectively, less than 10%
uploaded every time. If I cut down the diffing time by 1/3, the upload
goes to 30%, but that probably depends on the structure of a file in
question. If I stick to, say, a 300 second limit, almost the whole file
gets uploaded every time. The only way to find out is to experiment,
AFAIK.
